MURFREESBORO, AR (Ben Caxton) — A southwestern Arkansas park has lived up to its name again. An Arkansas teenager pulled at 7.44 karat diamond from the rocks along a stream at the Crater of Diamonds state park last week. Park interpreter Waymon Cox describes the diamond as pinto-bean sized and similar in color to coffee. The diamond is the 7th largest ever found at the site according to park officials. The park also claims to be the site of the largest diamond every unearthed in the United States, the 40.23 karat “Uncle Sam” diamond found in 1924. The finder of this diamond, Kalel Langford, is naming it after his own namesake and calling it the “Superman Diamond”.
